Difficulty installing sierra from USB

so a friend of mine gave me his MacBook till tomorrow. I downloaded sierra from the play store. installed it on it. updated it(not necessary for a bootable USB I know). I followed the instructions at tonymacx86.com except for the Scheme set to GUI (couldn't modify it ). I downloaded unibeast and multibeast. used unibeast to create a bootable USB. copied multibeast to the usb. set my main PC bios to default. turned off virtualisation and set secure boot to other OS. my pc configuration: X99 sabertooth with 5820k non overclocked 48gb of RAM gtx 980 ti sound blaster ZxR I tried to boot from the USB I made. went to clover. booted up from USB. first time showed Apple logo then loading screen that doesn't end then black screen. next time it goes through then shut down. I dont know whats wrong with it. I would like to see if I need to do anything using the mac before giving it back in 1 day. thanks in advance
